I would like to start daytrading altcoins, but I need to know which ones are best to work with.
If you are looking for coins with really high volatiliy then you just need to go to coinmarketcap.com and start looking at the project that are listed on rank 1000 or lower in terms of marketcap. Those projects usually fluctuate a lot price wise, but i don't really think that most of them are suitable for daytrading because usually they also have a pretty low trading volume and if you want to trade with big amounts then the impact of your own trades is to big. I generally would not look for coins with high volatiliy because in the crypto space almost every coin fluctuates enough to do daytrading.
for daily trading, it will be more suitable for coins with more stable fluctuations. because we will only look for small profits but are expected to occur continuously, so that later there will be large amounts of profit. why not choose eth for day trading, which has a large capitalization so that manipulation doesn't happen often
